Linguagem e formação de conceitos: uma leitura a partir da escola de Vigotski

The present study is the result of a master's research that aimed to highlight, within Vygotsky's work, the importance given to language in the concept formation process. This is a theoretical study, carried out through bibliographical research, being divided in two main moments. In the first one, when the author's Marxian legacy is retaken, the role played by the categories work and language for the process of formation of consciousness is presented. Such discussion is necessary to approach, in the second moment, the characteristics of the language and how the process of formation of concepts takes place. Such reflection will serve as a basis to signal, in the light of Vygotsky's theory, the importance of the teacher and the school in the humanization process of people.
